4. MICROSTRIP PATCH ANTENNA
 Microstrip patch antenna consists of a conducting patch and
ground plane between them is a dielectric medium called the
substrate
 The dimensions of a patch are smaller as compared to the
substrate and ground

9. HFSS SOFTWARE TOOL
HFSS is a high-performance full-wave electromagnetic(EM)
field simulator for arbitrary 3D volumetric passive device
modeling that takes advantage of the familiar Microsoft
Windows graphical user interface
 High Frequency Structure Simulator
 It was developed by Prof. Zontal Cendes and his student at
Mellon Univ. in 1989
 HFSS is commercial elements
 It is a method solver for electromagnetics

20. CONCLUSION
An antenna simulation is done on High Frequency
Structure Simulator HFSS. The design procedure begins
with determining the length, width, height of patch
plane by formulae. The obtained result of this antenna
is peak gain of 9.37db, peak directivity is 10.024db and
antenna efficiency is 93%, the minimum value of VSWR
for this antenna is 0.0210 at 6.0175 GHz resonant
frequency.
